The dynamic pressure characteristics of the cylinder bore in a hydraulic axial piston pump are important for understanding the fluid behavior and performance of the pump. The following are some key aspects related to dynamic pressure characteristics: 1. Pressure changes: The cylinder bore experiences dynamic pressure changes during pump operation. These pressure changes occur as the piston reciprocates within the cylinder bore, creating alternating areas of high and low pressure. Pressure changes directly affect the output flow and overall efficiency of the pump. Inlet and outlet pressure: The dynamic pressure characteristics in the cylinder are affected by the inlet and outlet pressure conditions of the pump. Inlet pressure determines the initial pressure at which fluid enters the cylinder bore and affects the pressure at which fluid exits the cylinder bore. The difference between inlet and outlet pressure creates a pressure gradient that drives fluid flow through the pump. 3. Piston movement and pressure distribution: The movement of the piston within the cylinder bore affects the pressure distribution along the length of the bore. As each piston reciprocates, it creates an area of high pressure on one side of the bore and a low pressure area on the other. As the piston moves, the pressure distribution is constantly changing, causing fluctuations in the pressure distribution within the cylinder bore. 90-R-055-KA-1-NN-80-S-3-S1-C-03-GBA-38-32-24 90R055KA1NN80S3S1C03GBA383224 90-R-055-KA-1-NN-80-S-4-C6-C-03-GBA-35-35-24 90R055KA1NN80S4C6C03GBA353524 90-R-055-KA-1-NN-80-S-4-S1-C-00-GBA-29-29-20 90R055KA1NN80S4S1C00GBA292920 90-R-055-KA-1-NN-80-S-4-S1-C-00-GBA-35-35-24 90R055KA1NN80S4S1C00GBA353524 90-R-055-KA-1-NN-80-S-4-S1-C-02-GBA-26-26-24 90R055KA1NN80S4S1C02GBA262624 90-R-055-KA-1-NN-80-S-4-S1-C-03-GBA-26-26-24 90R055KA1NN80S4S1C03GBA262624 90-R-055-KA-1-NN-80-S-4-S1-C-03-GBA-32-32-24 90R055KA1NN80S4S1C03GBA323224 90-R-055-KA-1-NN-80-S-4-S1-C-03-GBA-38-38-24 90R055KA1NN80S4S1C03GBA383824 90-R-055-KA-2-AB-60-S-3-C6-D-03-GBA-30-30-24 90R055KA2AB60S3C6D03GBA303024 90-R-055-KA-2-AB-80-S-3-C6-D-04-GBA-38-38-20 90R055KA2AB80S3C6D04GBA383820 90-R-055-KA-2-AB-80-S-3-S1-D-03-GBA-32-32-24 90R055KA2AB80S3S1D03GBA323224 90-R-055-KA-2-BC-60-L-4-S1-C-03-GBA-35-35-24 90R055KA2BC60L4S1C03GBA353524 90-R-055-KA-2-BC-60-P-3-S1-D-03-GBA-35-35-24 90R055KA2BC60P3S1D03GBA353524 90-R-055-KA-2-BC-80-L-4-S1-C-03-GBA-35-35-24 90R055KA2BC80L4S1C03GBA353524 90-R-055-KA-2-CD-80-L-4-S1-C-03-GBA-35-35-24 90R055KA2CD80L4S1C03GBA353524 90-R-055-KA-2-NN-60-D-4-S1-L-02-GBA-32-32-24 90R055KA2NN60D4S1L02GBA323224 90-R-055-KA-2-NN-60-P-3-S1-D-05-GBA-32-32-20 90R055KA2NN60P3S1D05GBA323220 90-R-055-KA-2-NN-80-P-3-S1-C-03-GBA-35-35-24 90R055KA2NN80P3S1C03GBA353524 90-R-055-KA-2-NN-80-R-4-S1-C-03-GBA-26-26-28 90R055KA2NN80R4S1C03GBA262628 90-R-055-KA-2-NN-80-S-3-C6-C-03-GBA-42-42-24 90R055KA2NN80S3C6C03GBA424224 4. Pressure pulsation: The pressure pulsation caused by the dynamic pressure characteristic refers to the small pressure fluctuation superimposed on the average pressure in the cylinder bore. Pressure fluctuations can adversely affect pump performance, such as increased noise, vibration and potential damage to system components. Minimizing pressure fluctuations is important for smooth and efficient pump operation. 5. Interaction between the valve plate and the cylinder block: The interaction between the valve plate and the cylinder block also affects the dynamic pressure characteristics of the cylinder bore. The valve plate controls the flow of fluid into and out of the cylinder bore, affecting the pressure distribution and flow rate within the pump. Proper design and precise alignment of the valve plate and cylinder block are critical to ensure optimal fluid dynamics and minimize pressure loss. 6. Leakage effect: Leakage in the pump, for example through the gap between the piston and the cylinder bore, will affect the dynamic pressure characteristics. Leakage will result in a reduction in effective pressure, resulting in reduced pump efficiency and potential performance loss. Minimizing leak paths and optimizing seal arrangements are critical to maintaining the required pressure levels within the cylinder bore. 7. Fluid compressibility: The dynamic pressure characteristics are affected by the compressibility of the pumped fluid. The compressibility of the fluid affects how pressure changes propagate down the cylinder bore, which can lead to changes in flow rate and system response. Considering fluid compressibility is important to accurately predict dynamic pressure behavior and optimize pump performance. 90-R-055-KA-2-NN-80-S-4-C6-C-03-GBA-42-42-24 90R055KA2NN80S4C6C03GBA424224 90-R-055-KA-5-AB-60-L-3-C6-C-03-GBA-35-35-24 90R055KA5AB60L3C6C03GBA353524 90R055-KA-5-AB-60-L-3-S1-D-03-GBA-35-35-24 90R055KA5AB60L3S1D03GBA353524 90-R-055-KA-5-AB-60-L-3-S1-D-03-GBA-35-35-24 90R055KA5AB60L3S1D03GBA353524 90-R-055-KA-5-AB-60-P-3-C6-C-03-GBA-35-35-28 90R055KA5AB60P3C6C03GBA353528 90-R-055-KA-5-AB-60-P-3-S1-C-03-EBC-23-23-24 90R055KA5AB60P3S1C03EBC232324 90R055-KA-5-AB-60-P-3-S1-C-03-GBA-35-35-24 90R055KA5AB60P3S1C03GBA353524 90-R-055-KA-5-AB-60-P-3-S1-C-03-GBA-35-35-24 90R055KA5AB60P3S1C03GBA353524 90-R-055-KA-5-AB-60-P-4-C6-C-03-GBA-35-35-28 90R055KA5AB60P4C6C03GBA353528 90-R-055-KA-5-AB-60-R-3-C6-D-03-GBA-26-26-20 90R055KA5AB60R3C6D03GBA262620 90R055-KA-5-AB-60-S-3-C6-C-03-GBA-26-26-20 90R055KA5AB60S3C6C03GBA262620 90-R-055-KA-5-AB-60-S-3-C6-C-03-GBA-26-26-20 90R055KA5AB60S3C6C03GBA262620 90-R-055-KA-5-AB-60-S-3-C6-C-04-GBA-35-35-24 90R055KA5AB60S3C6C04GBA353524 90-R-055-KA-5-AB-60-S-3-C6-D-03-GBA-26-26-24 90R055KA5AB60S3C6D03GBA262624 90-R-055-KA-5-AB-60-S-3-S1-C-03-GBA-23-23-24 90R055KA5AB60S3S1C03GBA232324 90-R-055-KA-5-AB-60-S-3-T1-C-03-GBA-35-35-20 90R055KA5AB60S3T1C03GBA353520 90-R-055-KA-5-AB-60-S-4-C6-C-03-GBA-32-32-24 90R055KA5AB60S4C6C03GBA323224 90-R-055-KA-5-AB-60-S-4-C6-C-03-GBA-35-35-24 90R055KA5AB60S4C6C03GBA353524 90-R-055-KA-5-AB-60-S-4-C6-D-03-GBA-35-35-24 90R055KA5AB60S4C6D03GBA353524 90-R-055-KA-5-AB-80-L-4-S1-C-03-GBA-35-35-24 90R055KA5AB80L4S1C03GBA353524 8. Pressure loss: The dynamic pressure characteristics in the cylinder bore involve the pressure loss due to various factors such as friction, fluid acceleration and flow separation.
